The fracture analyses for coke models reproducing the form of the non-adhesion grain boundaries were performed using the rigid bodies-spring model. The coke model was developed by the random arrangement of the coal particle polygons and expansion of the polygons based on experimental results. As a result, many springs at the gap or edge of the non-adhesion grain boundaries were fractured, and the arrangement and shape of the non-adhesion grain boundaries were supposed to affect the fracture of the coke. Furthermore, the coke with the larger blending ratio of the low-quality coal fractures with the weaker strength. This is because the number of the non-adhesion grain boundaries increases, and the size of the boundaries becomes larger and the shape of the boundaries becomes complex.
